Former Auburn RB Roc Thomas received a three-game suspension from the NFL for a violation of the league’s substance abuse policy. However, he is allowed to participate in training camp and the preseason.

Police reportedly found 143 grams of marijuana and nearly $16,000 in cash at his apartment on Jan. 16, Pro Football Talk reported. A search warrant was executed after there were complaints about the smell of marijuana.

Thomas admitted to felony marijuana possession in May but was sentenced to probation, with the charge dismissed if he completes conditions of the probationary term. Those include a chemical dependency evaluation and possible treatment; no alcohol or drug use; and random testing.

Thomas, 23, played in five games last season and had 10 touches for 51 yards. He played 29 snaps on offense and 59 on special teams. He had eight carries for 30 yards.
